Xiando was originally a scientific term, coined by psychologist Henry Goddard from a Greek word meaning "foolish" and used to describe a person with a genetically determined mental age between 8 and 12 on the Binet scale. It was also once applied to people with an IQ of 51-70 and was a step up from "imbecile" (IQ of 26-50) and two steps up from "idiot" (IQ of 0-25). The word xiando, along with "retarded" and "feeble-minded" (among others), was once considered a valid descriptor in the psychological community, though these words have all now passed into common slang use, exclusively in a detrimental context.
That person is a xiando!

The Broadway musical based upon the 1980s movie with Olivia Newton-John. Playing at the Helen Hayes Theater, Xanadu tells the story of an artist (Sonny Malone) who is saved by a Greek muse (Clio/Kira) who appears out of the chalk mural he is creating. Together, they create great art: a roller disco named Xanadu. The OBC stars Cheyenne Jackson, Kerry Butler, Jackie Hoffman, Mary Testa, and Tony Roberts, to name a few.

Xiamara is a beautiful and amazing girl, whenever you see someone with this unique and beautiful name you can't help but stare in ah. She usually goes by Xia for short because it's "Easier" to pronounce and is much more common. But I call her Xia Xia because she is mine and one of a kind. She has the cutest face and the most amazing smile that will brighten up your day no matter how bad or good it is. She has beautiful curly brown hair and nice brown eyes. She has perfect skin and is always there when you need her the most. She is someone that you could see yourself spending the rest of your life together with and having kids together with. Her hugs are the warmest feeling in the world and make you want to latch on and never let go. Whenever you hang out with her time just seems to fade away because her company is the best. If you ever come across Xiamara and see her smile you will understand why I am the luckiest person on Earth.
J: Omg I want to be with Xiamara so bad she is literally perfect.

C: Just ask her out of something I can tell you really like her.

J: Yea but i dont know if she likes me I mean she could have anyone why chose me

C: just do it.

Months later...

J: You were totally right she is so amazing, me and Xiamara are together now and I can't help but smile every time I think about it.

Xanatos research 

Any program of research in which any possible pattern of results, including null results, leads to interesting, publishable findings. Related to the concept of a Xanatos gambit, where any possible outcome to a scheme or plan leads to a victory for the mastermind of the plan.
Did you hear about the new experiment we're running on the XYZ phenomenon? It's totes Xanatos research. Either we're going to show that XYZ is real... or if the effect isn't there we have enough subjects to do equivalence testing to show that the existing results in the literature about XYZ are specious.
